Answer:
1. Global warming (as we pass a threshold, it may be irreversible)
2. Reduce the emission of greenhouse gases
Explanation:
Climate change is a general phenomenon associated with the effects of global warming caused by anthropological activities, especially the emission of greenhouse gases (e.g., carbon dioxide, methane, nitrous oxide, etc). It has been shown that global warming is causing an increase in the temperature on the planet at a speed unprecedented since the beginning of the Industrial Revolution. The increase in greenhouse gases in the atmosphere is a direct consequence of human activities, especially from the use of fossil fuels in electricity, heating, transportation, etc. In consequence, it is possible to reduce the impact of global warming by using renewables climate-friendly energy resources, for example, by using solar panels for electricity, solar water for heating and eolic energy for industry (electricity). In this context, it should be taken into account that global warming may be irreversible, and we have the tools to stop it before it is too late.
